10VDC output during operation. This setpoint is adjustable from 0% to 50% (0%=0,0VDC,
50%=5,0VDC).
Inverted operation. It is possible to invert the 0-10VDC output on the ES10, i.e. when the
requirement for air volume is low, the 0-10VDC output voltage is increased instead of
decreased. This is set in the setpoint menu no. 14. The value
”0” = Normal output, the value
”1” = Inverted output.
Frequency converter / Triac controller. The choice of frequency converter or triac controller
as motor controller is set in the setpoint menu no. 16. The value
”0” = Frequency converter,
the value
”1” = Triac controller. If ”triac controller” is selected in setpoint menu no. 16, the
setpoint menu no. 17 must be adjusted. In this setpoint the size of the sudden pressure
increases that may occur in the ventilation system are to be set. This value is adjustable
from 0 to 1000Pa or from 0.00m/s to 10.00m/s.
3.7 Pressure or flow transducer
Standard. The ES10 is able to control air pressure or air flow by means of the associated air
pressure or air flow transducer. This transducer is fitted on clamp 5 (0VDC), clamp 6
(+24VDC), and clamp 7 (0-10VCD pressure/air flow input).
An optional pressure transducer ES11 is available as accessory to the ES10. If the ES11 is
used, it is not necessary to adjust the setpoints concerning the pressure sensor as these
have been set at the factory. The measuring range of the ES11 is 0Pa to 500Pa.
Other transducers. If a different air pressure or air flow transducer is chosen, the setpoint
menu no. 12 and no. 13 are to be set. In setpoint menu no. 12, the pressure or airflow which
the chosen sensor measures, is adjusted when the sensor output is 10VDC. This setpoint is
adjustable from 0Pa to 5000Pa or from 0.00m/s to 50.00m/s. Example: If a pressure
transducer at an output of 10VDC measures 500Pa, then 500Pa must be entered in the
setpoint menu no. 12.
In setpoint menu no. 13, the voltage output of the air pressure or the air flow transducer at
0Pa respectively 0m/s is adjusted. This setpoint is adjustable from 0.0V to 10.0V.
Example: If a pressure transducer measures 0Pa at 1.0V. This value must be entered in
setpoint menu no. 13.
3.8 Language
The menu language is available in Danish and English. The language is set in setpoint
menu no. 18. Value
”0” = Danish and value ”1” = English.
3.9 PID controller
Air pressure or air flow adjustment is controlled by a PID controller. The PID controller is
equipped with 4 setpoints in the setpoint menu.
1) Setpoint no. 19. PID KP. The amplification of the PID controller.
2) Setpoint no. 20. PID TI. The integration time of the PID controller.
3) Setpoint no. 21. PID H. The sampling time of the PID controller.
